Yes, you can bring food on a plane. Solid food goes in a carry-on or a checked bag. Food that is a liquid, gel, paste or spread has to be 3.4 oz (100 ml) or less in a carry-on, or it goes in your checked bag.
That one test sorts almost everything. If you can pour it, spread it, spray it or squeeze it out of a container, treat it as a liquid. This guide follows TSA's "What Can I Bring?" food pages as they read on October 12, 2026.
The one-question test: can you spread it?
TSA's food guidance says solid food items can travel in carry-on or checked bags, while liquid or gel food items larger than 3.4 oz are not allowed in carry-on bags and should go in checked bags if possible. The rule behind it is the same 3-1-1 liquids rule that covers shampoo and toothpaste. Our guide to TSA liquids and battery rules explains the quart-bag mechanics.
The surprising cases are the foods that people think of as solid but TSA classes as spreadable. Cream cheese, peanut butter, jam and hummus are all in that group.
What is allowed in a carry-on, item by item
| Food | Carry-on | Checked bag |
|---|---|---|
| Bread, pizza, pies and cakes | Yes | Yes |
| Cookies, crackers, candy, cereal | Yes | Yes |
| Nuts and dried fruit | Yes | Yes |
| Solid cheese | Yes | Yes |
| Fresh eggs | Yes | Yes |
| Cooked meat, seafood or vegetables (no liquid) | Yes | Yes |
| Fresh fruit and vegetables | Yes (see exception below) | Yes |
| Creamy cheese, creamy dips and spreads | Up to 3.4 oz | Yes |
| Peanut butter, jam, jelly, honey | Up to 3.4 oz | Yes |
| Hummus, gravy | Up to 3.4 oz | Yes |
| Ice cream | Up to 3.4 oz | Yes |
| Juices | Up to 3.4 oz | Yes |
| Canned foods | Special instructions | Yes |
The "up to 3.4 oz" items also have to fit in your single quart-sized bag with your toiletries. A 3.4 oz jar of jam and a 3.4 oz tube of toothpaste share the same bag.
The honest negative: canned food is a gamble
TSA lists canned food as allowed in carry-on "with special instructions". In practice that means a can can trigger additional screening because of how it looks on the X-ray or because of the liquids rule, and it may be refused at the checkpoint. TSA's own advice is to pack it in your checked bag, ship it to your destination, or leave it at home. A tin of tuna in oil is exactly the kind of item that ends up in the bin.
Frozen food, ice packs and dry ice
- Frozen food: Meat, seafood and vegetables are allowed in carry-on and checked bags. If they are packed with ice or ice packs, those have to be completely frozen at the checkpoint. If there is any liquid at the bottom of the container, TSA says it will not be permitted.
- Gel ice packs: Frozen liquid items are allowed as long as they are frozen solid when presented for screening. Partially melted or slushy packs must meet the 3-1-1 rule. Medically necessary gel ice packs in reasonable quantities are allowed in any state.
- Dry ice: TSA lists dry ice as "check with airline" for both carry-on and checked bags. The FAA limit is 5.5 lb (2.5 kg) of dry ice, packaged in a vented package and marked, and airline approval is required.
A cooler packed at 6 a.m. and carried through a 9 a.m. checkpoint usually survives. A cooler packed the night before, then sitting in a warm car, does not. Freeze everything solid and pack the ice packs on the outside, where you can show them.
Baby food, formula and breast milk
Baby food, formula and breast milk are the exception to the 3.4 oz rule. TSA allows them in carry-on in quantities greater than 3.4 oz (100 ml), and they do not need to fit in the quart bag. You should tell the officer at the start of screening and take them out of your bag for separate screening. You can ask that they not be X-rayed or opened, but expect additional screening. Ice packs and gel packs used to cool them are allowed in carry-on as well.
Fruit and vegetables: a domestic and a destination question
TSA allows fresh fruit and vegetables in carry-on and checked bags within the continental United States. The exception TSA names is flights from Hawaii, Puerto Rico or the U.S. Virgin Islands to the mainland, where most fresh fruit and vegetables cannot be taken because of the risk of spreading invasive plant pests.
For international arrivals, TSA's pages do not cover what customs will allow. Customs authorities in many countries restrict fresh produce, meat and dairy, and the rule is set by the country you land in. Check that country's customs website, or eat the fruit before you land.
Alcohol with your snacks
TSA allows alcohol in carry-on in containers of 3.4 oz (100 ml) or less, inside the quart bag. In checked bags, alcohol between 24% and 70% is limited to 5 liters per passenger in unopened retail packaging, and alcohol above 140 proof is not allowed in carry-on or checked bags.
How to pack food so security is quick
- Put it on top. TSA officers may ask you to separate food, powders and anything that clutters the X-ray image. If your food is at the top of the bag, that takes ten seconds.
- Use clear containers. A sandwich in a clear box or a transparent bag is easy to see. A foil-wrapped parcel is not.
- Count the spreads. Anything you could spread with a knife gets 3.4 oz or less.
- Keep it inside your personal item. A small food bag under the seat is easier to reach than a snack buried in a carry-on in the overhead bin. If you are deciding what goes where, our guide to carry-on vs personal item explains the difference, and the carry-on size chart by airline lists the limits.
Frequently asked questions
Can I bring a sandwich through airport security? Yes. A sandwich is a solid food, and TSA allows solid food in carry-on and checked bags.
Can I bring cheese on a plane? Solid cheese, yes. Creamy cheese is limited to 3.4 oz in a carry-on.
Can I bring peanut butter on a plane? Yes, in a container of 3.4 oz (100 ml) or less in your carry-on, or any size in your checked bag.
Who makes the final call? The TSA officer at the checkpoint. TSA says the final decision on whether an item is allowed rests with the officer, so a food that is listed as allowed can still be refused.
